Yes. Note that I was testing on i386, which has hard limit 4 GiB on 
virtual memory.

I also tested git master on an arm64 machine with 24 GiB of RAM. There, 
info didn't run out of memory (it allocated "only" ~5 GiB...), but it 
also never finished, because I ran out of patience after 20 minutes or 
so.
